Dear,

First give a comfort to settle, ask her to comedown to your cabine

Treat her as your friend, ask her the feelings of the company from the day she join, any problem with colleagues, peers, work, Operations. share your view about the company and about her. Speak about her positives you find in work,as person expect the puntuality. Ask her personal problem as a friend any problem in family, personal, travelling check the reason why she is not able to come on time. give a solutions for it, say the important of the punctuality. Depends upon your approach towards her

Hope this could give more comfort and care to share the views and sort this problem

Same problem i faced, this action helped me alot. Now i don't have any problem with the attendance, timing and leave
